XVILLIAM H. BYRAM, OF NEW YORK, ASSIGNOR OF ONE-HALF TO JOHN BEDMAN, or FISHKILL LANDING, N. Y.

BOILER FOR HEATING BUILDINGS.

SPECIFICATION forming part of LettersPatent No. 304,609, dated September 2,

Application filed December 6, 1883. o model.)

To all whom it may concern Be it known that 1, WILLIAM H. the city, county, and State of New York, have invented certain new and useful Improvements in Boilers for Heating Buildings and other Purposes, of which the following is a full, clear,

and exact description.

This invention relates to boilers composed of a series of sections mounted one upon the other for use either in heating and circulating water or for generating and circulating steam, to be used in heating for other purposes. It has more for its object the production of an efficient and economical sectional boiler, tain a positive circulation and be comparatively or wholly free from leakage, separate and detachable tubes, liable to produce leakage, being avoided in its construction.

Ilhe invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a vertical section upon the line 00 00 in Fig. 2 of a boiler embodying my invention; Fig. 2, a further vertical section upon the line 3 y in Fig. 1 of the same; Fig. 3, a horizontal section upon the line 10 w in Fig. 2, and Fig. 4 a further horizontal section upon the line 2 z in Fig. 2. Fig. 5 is a vertical section, upon a larger scale, of two of the boiler-sections in part in illustration of the mode of connecting the water-ducts of said sections. Fig. 6 is a further vertical section in a plane at right angles to Fig. 5, upon the same reduced scale as Figs. 1, two of the boiler-sections, showing the application to or on the water-ducts of certain draftand Fig. 7, a view in perof said plates detached.

This section, as B,

The sections B B are each constructed with upper and lower marginal portions or ledges, d d, to provide for the support of the several sections of the boiler, one upon the other, and to give a flush finish to the sides of the boiler. necessary, have putty or .cement applied to them to prevent leakage, or they may be made close-fitting without any such filling, and the several sections are firmly held or bound to- 0, arranged to pass through sections B B have each cast on or with them a series of parallel horizontal water-ducts, G G, of a hollow bar-like construction in their transverse section, tapering or diminishing downward. These hollow tapering barlike water-ducts O G, which are formed in part of upper and lower diaphragms cast on or with the sides of the section, are arranged staggering in vertical relation with each other-that is, the several intermediate ducts-whereby the ducts of either one section will be over the flue or fire spaces g between the ducts of the section immediately above or below it, thus establishing a series of tortuous vertical courses between and under and over the ducts for heating gaseous products of combustion from the fire-box A to the smoke-outlet D, said waterducts only being of such depth as to provide for a free passage of' the heated gases over and under as well as between them. The tapering configuration of the fluespaces g as formed by the transverse shape of the ducts O 0 cases the passage of the heated gases from the one boiler-section to the next one above it. Furthermore, the series of waterducts O O in each section are in free commu nication with each other at their opposite ends all around the sides of the boiler within the as clearly shown in Fig. 4, and such water-spaces of the difierent sections are alternately connected above and below, on opposite sides of the boiler, by the tubular projections or nozzles h h, from or b b, its on the under side of the one boiler-section and upper side of the next boiler-section, so that they fit or bear one upon the other. These form sockets, being The joints thus formed may, if

They may be introduced into the boiler when fitting the sections together, or by removing the boiler-sections for the purpose; or
